Abstract
The utility model discloses a fireproof vacuum packaging film, which comprises a vacuum base film, wherein fireproof coating films are covered on the upper and the lower of the vacuum base film, a vacuum bottom oil layer is arranged below the lower layer fireproof coating film, an aluminum film layer is arranged below the vacuum bottom oil layer, and a protection film layer is arranged on the upper layer fireproof coating film. The fireproof vacuum packaging film can achieve excellent vacuum sealing, improves excellent flame retardant properties of packaging materials at the same time, and can be applied in sealing packaging of high-end electronic products and parts with gas insulation and fire prevention requirements.
Description
Technical field
The utility model relates to a kind of membrane material, relates in particular to a kind of vacuum-packed membrane material that can be used for fire line.
Background technology
Packaging film consumption in people's productive life is huge, and different packing materials has proposed different requirements to packaging film, and when guaranteeing mechanical strength, the membrane material with various different functionalities is all required and develops.What vacuum diaphragm can effectively prevent air enters and then realizes the specific functions such as antibacterial, antioxygen, is widely used in food, industrial goods, precision metallic parts etc.Yet multiple different vacuum diaphragm does not have fire-retardant function, when meeting with naked light, be easy to combustion-supporting and destroy the article of packaging, when packing valuables, increased the risk of its destruction.The vacuum diaphragm that can realize anti-flammability is still very rare.
Utility model content
The technical problems to be solved in the utility model is, overcomes the above-mentioned defect that prior art exists, and a kind of vacuum diaphragm with good flame-retardance is provided.
The utility model solves the technical scheme that its technical problem adopts:
The composite evacuated packaging film of preventing fires, comprises vacuum basement membrane, and vacuum basement membrane is respectively equipped with upper strata fire prevention film layer and lower floor's fire prevention film layer up and down, and lower floor's fire resistant coating film has oil reservoir at the bottom of vacuum, and at the bottom of vacuum, oil reservoir has aluminum membranous layer.Upper strata fire resistant coating film is provided with protective film.
Further, described vacuum basement membrane is two-layer compound vacuum diaphragm.For double-layer coextrusion film, upper strata is dura mater, can select nylon (PA) film, PETG (PET) film, and lower floor is mantle, can select polyolefin film, as non-bi-directional stretching polyethylene film, polypropylene screen etc.Preferably, mantle is near packing material.
Further, described fire prevention film layer is amino transparent fireproof coated film.Its typical preparation method is: by amino resins and the composite film forming of polyphosphate, wherein polyphosphate can adopt the polyethylene glycol (PEG) of different chain length and polyphosphoric acids (PPA), polyalcohol to synthesize.This coated film has the feature of excellent pliability, crack resistance and anti-flammability.
Further, described protective film is polyester rete.Can be Merlon (PC) film, PETG (PET) film etc.
Further, described fire prevention film layer is overlying on vacuum basement membrane by spraying or applying, and described protective film is combined by adhesive and upper strata fire prevention film layer, and aluminum membranous layer is overlying at the bottom of vacuum under oil reservoir by evaporation.
The beneficial effects of the utility model are: at the bottom of basement membrane, vacuum, oil and aluminium film can guarantee that composite membrane has excellent vacuum and mechanical property.Double-deck fire resistant coating film can guarantee that film is not lighted in naked light, and is conducive to equally the raising of vacuum leakproofness.The flexibility of the combination between each layer and characteristic assurance composite membrane, good in conjunction with being closely difficult for layering and vacuum and anti-flammability.
Accompanying drawing explanation
Fig. 1 is the utility model one example structure schematic diagram.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
With reference to Fig. 1, the composite evacuated packaging film of a kind of fire prevention, comprises vacuum basement membrane 1, and vacuum basement membrane is covered with respectively upper strata fire resistant coating film 2 and lower floor's fire resistant coating film 3 up and down, and lower floor's fire resistant coating film 3 has oil reservoir 4 at the bottom of vacuum, and at the bottom of vacuum, oil reservoir 4 has aluminum membranous layer 5.On the fire resistant coating film of upper strata, 2 are provided with protective film 6.
Described space base film 1 is PA (nylon)/PE (polyethylene) two-layer compound vacuum diaphragm.
Described upper and lower fire prevention film layer 2,3 is amino transparent fireproof coated film.The preparation method of the present embodiment floating coat is: by amino resins and polyphosphate, by the composite film forming of the mass ratio of 60:40, wherein polyphosphate can adopt polyethylene glycol (PEG) and polyphosphoric acids (PPA), polyalcohol synthetic.
Described protective film 6 is PETG film (PET) film.
Described upper strata fire prevention film layer 2 and lower floor's fire prevention film layer 3 are overlying on vacuum basement membrane 1 upper and lower surface by spraying, and described protective film 6 is by film layer 2 combinations of preventing fires of adhesive and upper strata, and aluminum membranous layer 5 is overlying at the bottom of vacuum oil reservoir 4 times by evaporation.
The thickness of described vacuum basement membrane 1 is 0.1mm, and the thickness of upper and lower layer fire resistant coating film 2,3 is 0.08mm, and the thickness of protective film 6 is 0.1mm, and at the bottom of vacuum, the thickness of oil reservoir 4 is 0.03mm, and the thickness of aluminum membranous layer 5 is 0.05mm.
Above a kind of preferred embodiment of the present utility model has been done to detailed introduction.The described specific embodiment is just for helping to understand core concept of the present utility model.It should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model principle, can also carry out some improvement and modification to the utility model, these improvement and modification also belong to the protection domain of the utility model claim.
